Abstract
Official abstract text for this publication.
A noise elimination device includes a low pass filter unit, a noise filtering unit and a signal synthesis unit. The low pass filter unit generates a low frequency image signal by separating low frequency elements from an input image signal. The noise filtering unit generates a filtered image signal by suppressing noise in the low frequency image signal in horizontal and vertical directions. The signal synthesis unit generates an output image signal by combining the high frequency image signal and the filtered image signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A noise elimination device, comprising: a low pass filter unit configured to generate a low frequency image signal by separating low frequency elements from an input image signal; a high frequency separation unit configured to generate a high frequency image signal by separating high frequency elements from the input image signal using the low frequency image signal; a noise filtering unit configured to generate a first filtered image signal by performin…
